Anyone good in Physics?

i was needing some help with some homework...kinda lazy to solve it...well cuz i dont know how...

1.A conical pendulum is formed by attaching a 0.900 kg ball to a 1.00 m-long string, then allowing the mass to move in a horizontal circle of radius 40.0 cm. The figure shows that the string traces out the surface of a cone, hence the name.

whats the tension of string and angular velocity?

physics is cool but as soon as class is over that shit goes out the window till i go back to class

physics is the reason i didn't go into engineering. Well, that and calculus...I hate higher level math

cramster?

i can't remember but isn't Tension just the opposite of gravity for this situation (.9 x 9.8)?

edit: wait no you need to find the angle the string is at...that's not very tough though..

Is the velocity constant?

Is the velocity constant?

that means a=0

that's all i've learned tbh

I love Physics

I love gettin' physical.

Let's get into physical.

Let me hear your body talk, body talk.

just draw out your free body diagram and break up the vectors into x and y components annd your should be able to find the x and y comps on your tension vector. do a little vector algebra to find the magnitude of the T vector.

remember the x-comp is the manitude times cos(theta) and y is sine
